Clement was the fourth Bishop of Rome after Peter, Linus and Cletus. He lived towards the end of the first century, but nothing is known for certain about his life. Clement’s letter to the Corinthian church has survived. It is the first known Patristic document, and exhorts them to peace and brotherly harmony.

Liturgical colour: green

The theological virtue of hope is symbolized by the colour green, just as the burning fire of love is symbolized by red. Green is the colour of growing things, and hope, like them, is always new and always fresh. Liturgically, green is the colour of Ordinary Time, the season in which we are being neither especially penitent (in purple) nor overwhelmingly joyful (in white).

Avoid getting into debt, except the debt of mutual love. If you love your fellow men you have carried out your obligations. Love is the one thing that cannot hurt your neighbour; that is why it is the answer to every one of the commandments.

Be quick to listen but slow to speak and slow to rouse your temper; God’s righteousness is never served by man’s anger. Nobody must imagine that he is religious while he still goes on deceiving himself and not keeping control over his tongue; anyone who does this has the wrong idea of religion.

You must be scrupulously careful as long as you are living away from your home. Remember, the ransom that was paid to free you was not paid in anything corruptible, neither in silver nor gold, but in the precious blood of a lamb without spot or stain, namely Christ.
